The aim of this study was to acquaint with smart temperature sensors from different producers and to study their properties. The following step was to choose a suitable temperature sensor and a microcontroller (MCU) for measuring and temperature processing. On the market there are products from different firms such as Analog Devices, Microchip, Dallas, Maxim, National Semiconductor, Texas Instruments, Smartec etc. All those firms offer not only temperature sensors, but also microcontrollers. Every producer has its own realization of the inter-sensors communication. In this study there are introduced a wiring diagram of a microcontroller driven module for a temperature measuring making use of a smart temperature sensor and also designs of pr...
